(415) Unsupported Media Type when POST a Import

[MCalegher]

I'm in the process of trying to begin integrating HubSpot with an external application from which I am trying to upload CSV formatted data to create an import .

Language: Python

url = "https://api.hubapi.com/crm/v3/imports"
headers = {
        'authorization': 'Bearer %s' % ApiKey,
        'Content-Type': 'application/json'
    }
response = requests.request("POST", url,headers=headers, data=payload, files=files)

the payload is

{
    "name": "IMPORT xxx",
    "dateFormat": "DAY_MONTH_YEAR",
    "files": [
        {
            "fileName": "import_xxx.csv",
            "fileFormat": "CSV",
            "fileImportPage": {
                "hasHeader": True,

                ]
            }
        }
    ]
}

the file is a correct CSV

I update the authorization method of your integration's API requests with doc at: migration 

Then error is:

415 Client Error: Unsupported Media Type for url: https://api.hubapi.com/crm/v3/imports

Unfortunately the documentation is not complete....

Imports Doc 

From this information, can you see any issues in what I am doing? Please let me know if more information is required.

Hi, @MCalegher 👋 Can you set your Content-Type header to 

multipart/form-data

and try again? 

I found it in the documentation, but it was a bit tucked away — “For the request header, add a Content-Type header with a value of multipart/form-data.”

Hey, @tominal, am I missing anything obvious here?

 Best,

Jaycee

Thanks😀

I would bet that's it!
